Extensor Tendon Injuries in the Athlete.

An athlete's hands are susceptible to a variety of acute and cumulative traumas depending on their chosen sport. Depending on the timing of the injury, the immediate requirements of the athlete, and future aspirations, treatment strategies may need individual customization. This article offers a brief review of the anatomy and complex function of the extensor mechanism, discusses the etiologies of various extensor injuries, and outlines the multiple treatment options and expected outcomes.

Ewing Sarcoma in an Infant Metacarpal.

We describe a case of Ewing sarcoma in the metacarpal of a 5-month-old male. After pain, erythema, and swelling of the hand failed to resolve with antibiotics, radiographs and magnetic resonance imaging raised suspicion for a neoplastic condition. Open biopsy confirmed the diagnosis of Ewing sarcoma and treatment with chemotherapy and surgical resection was initiated.

The Relationship of Multiplanar Distal and Uniplanar Proximal Interlocking Screws to Neurovascular Structures with the Depuy Synthes Humeral Nail-EX: An Anatomic Study.

Objective: To determine the proximity of neurovascular structures to multiplanar distal interlocking screws and proximal interlocking devices for an antegrade inserted humeral nail.

Methods: Humeral nails (Depuy Synthes Humeral Nail-EX, Paoli, PA) were inserted into 10 matched cadavers with 3 distal interlocking trajectories: anterior to posterior (A-P), anterolateral to posteromedial, and anteromedial to posterolateral (AM-PL). The distance of the screw path and screw head to the radial, lateral antebrachial cutaneous nerve (LACN), and median nerves and the brachial artery was measured.

All-Arthroscopic Treatment of Dependent Osteochondral Lesions of the Ankle: Surgical Technique.

A large number of articular cartilage defect treatments have been described. However, few have discussed the use of biologic agents implanted into the so-called dependent defect arthroscopically. Furthermore, even fewer of these reports have contained a description for treating dependent osteochondral lesions of the tibial plafond.
